Android: If you're an active Redditor with an Android phone or tablet consider installing BaconReader; a Reddit client that makes it easy to browse, comment, and create new topics as well as upload images from your phone directly to Imgur.

The client is well-optimized for Android—you can swipe a comment to upvote, downvote, check the user's profile, or open a linked item in a post. The top of the screen has two pull-down menus; one for your chosen Subreddit and the second to filter by rating, newness, what's hot, etc. I also like that the comments are color coded so it's easy to figure out where the comment is in the reply hierarchy.

The app is well designed and free if you're willing to put up with a banner ad or you can upgrade to the premium version for $1.99. All in all it's a much nicer way to use Reddit from your phone over navigating the full site in a mobile browser.
